This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. MWP1 is a very usually shaped, unusually large, and unusually old, planetary nebulae. The progenitor star is also one of the hottest stars known, so hot it is producing large amounts of X-rays. The image was generated with observations in the Oxygen [OIII] (blue) and Hydrogen-Alpha (orange) filters. In this image, North is up, East is to the left.

The lovely, symmetric planetary nebula cataloged as MWP1 lies some 4,500 light-years away in the northern constellation Cygnus. One of the largest planetary nebulae known, it spans about 15 light-years. Based on its expansion rate the nebula has an age of 150 thousand years, a cosmic blink of an eye in the 10 billion year life of a sun-like star. But planetary nebulae represent a very brief final phase in stellar evolution, as the nebula's central star shrugs off its outer layers to become a hot white dwarf. In fact, planetary nebulae ordinarily only last for 10 to 20 thousand years. As a result, truly ancient MWP1 offers a beautiful challenge to astronomers studying the evolution of its central star.
